A 41-year-old Romanian woman was arrested late on Tuesday at Kos airport on suspicion of helping a young migrant from Afghanistan leave the country.
The woman was arrested after pretending to be the boy’s mother.
The minor was set to travel to Belgium with her using a fake passport.
The child, aged 13, was taken into care by the police at Kos airport, while the 41-year-old was due to face a magistrate on Wednesday.
Meanwhile, a 45-year-old Pakistani man, a 22-year-old woman from Pakistan and her child were stopped in Santorini on suspicion of a similar scam.
The two adults were pretending to be a couple traveling to Brussels but the 45-year-old was suspected of being a trafficker helping the woman reach Belgium.
